Practical joke or stage attraction? (3-4)
I believe the answer is:
leg-pull
'practical joke' is the definition.
(I've seen this before)
'stage attraction?' is the wordplay.
'stage' becomes 'leg' (a leg is a stage of a competition).
'attraction?' becomes 'pull' (I've seen this in another clue).
'leg'+'pull'='LEG-PULL'
'or' acts as a link.
(Other definitions for leg-pull that I've seen before include "Hoax exerted on lower limb?" , "Trick; practical joke" , "Informal hoax involving lower limb" , "Jolly jape involving lower limb" , "A hoax, tease" .)
